Application filed February 20, 1915.

rl`lie present invention relates to improve ments in quick acting' wrenches.

ln carrying out our invention we propose to construct a wrench which may be atljnsted to nuts, pipes or other work within a wide range ot sizes which in operation may be easily manipulated to engage with or to be withdrawn 'from the work, so as to tighten or loosen the same and also whereby the jaws of the wrench may obtain fresa holds in an expeditious manner.

lille also aim to construct wrench wherein both of the jaws will be simultaneouslyV moved toward the obje `t to be engaged.

lt is a still further object ot the invention to construct a wrench which shall embody two jaws, each of the said jaws resting upon the other to provide bearings therefor, a cai'- riage or casingn being' arranged to receive the shan is of the said jaws, the said carriage having pivoted therein a handle having` an annular end provided with teeth which are adapted to engage with teeth provided upon the shanks of the jaws, and the carriage being so constructed as to limit the movement of the jaws either in an open or closed position.

lll" ith the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the 'following specification and falling within the scope of the appended claim.

ln the drawings: Figure l is a side elevation of a wrench constructed in accordance with the present invention and showing?, the jaws of the same in their open position, Fig. 2 is a similar View showing` the jaws closed, Fig. 3 is a transverse sectional view approximately on the line 3-8 oit Fig. 9 Fig. a is a longitudinal sectional view approximately on the line -l of Fig. 2, Fig. 5 is a side elevation illustrating` one of the side plates of the carriage removed and showing the manner in which one of the aws is adjusted with relation to the other jaw so as to Patented Dee. 25., leila.

lengthen the range of stroke between the said jaws, Fig. 6 is a perspective view of one of the members comprising` the carriage or casing, and Fig. 7 is a perspective view of one of the jaws.

Referring now to the drawings in detail, the numeral l designates a wrench constructed iii accordance with the present invention.. The wrench includes two jaws which we will terni outer and inner jaws` the said outer jaw being` indicated by the numeral and the inner jaw being,` indi ated by the numeral 3. Each of the jaws is provided with an angular shank 4l, the said shanks, adjacent the jaws 2 and 3 being centrally reduced to provide each of said Shanks upon its opposite sides with transverse shoulders 5 and 5 respectively. The Shanks are adapted to have their adjacent edges contact with each other but the ends of the said Shanks adjacent thel opposite jaws Yformed thereon have their adj acent taces reduced er cut-away and the ineinbers provided by the said cut-away portions are rormed with teeth 6 and 6 respectively.

The ni'lineral l' designates a casing or carriage, the same preferably comprising` two similar members, each ofA which being,- formed with a central longitudinal recess or channel 8 so arranged that the outer longitudinal edges ot' 4the shanks of thev wrench will engage therewith, but also whereby the said Shanks, when the members comprising the casing are assembled will engage with the opposite faces oi the recess or channel, thus insuring` a positive longitudinal movement of the jaws ot the wrench in a. manner which will presently be described. Arranged within the channels 8 of the carriage or casini;l 7 is the head 9 provided upon one end. of a handle 10. The head is formed with a rounded periphery, and the said periphery is provided with teeth 11, the said teeth cowacting with the teeth 6 and 6 ot the Shanks of the respec tive jaws l and 2. The carriage 7, at its inner end, is cut approximately centrally in a. longitudinal direction and transversely from one of its edges, providing a substantially rectangular cut-away portion. The inner walls of the said cut-away portion provide shoulders l2 which are adapted to be contacted by the shoulders 5 oi the jaws 3, when the jaws are spread apart, while the end of the carrie. 0e forward of the shoulders 12 provides contact members with which the shoulders 5 of the jaw member 2 abut when the handle actuates the jaws to bring the same toward each other and when an obstacle is not engaged between the aws.

It will be noted, from the above description, that the shoulders are normally adapted to contact with the shoulders provided by the end .f the carriage to limit the movement of the jaws in both an inward and an outward di iection, but it will be noted by reference to Fig. 5 of the drawings that either or both of said jaws may be adjusted within the earria Oe to lengthen the space between the jaws, and thus readily adjust the jaws to compensate for their engagement with the articles of varying sizes. It is to be further understood that the carriage or casing is separable, the same being preferably-secured by means of screws or the like, so that by removing one of the sections of said carriage or casing, the adjustment of the jaws may be readily and quickly regulated.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertaii'is without further detailed description.

Having thus described the invention, what we claim is:

In a wrench of the class described, two jaws having angular Shanks, comprising re` duced members projecting from the jaws and forming shoulders upon each of the sides of the jaws, said shanks haring their adjacent edges opposite their jaws reduced and provided with teeth, a carriage including` a hollow member for receiving the shanlfs, said hollow member havingf outer edge formed with a reduced portion providing a stop for the shoulders of one ol the jaws and the end of said carriage Alormed. with the reduced portion providing a stop for the shoulders of the second jaw, a handle haring a peripheral head received within the carriage and pivotally secured thereto and said head being provided with teeth which co-act with the teeth ol2 the Shanks.

In testimony whereof we alix our signatures in presence of two witnesses.
